• solar lights at Palmerston District Primary School - estimated cost of $12,200.

3) The benefits of the environmental sustainable initiatives to be undertaken at ACT public schools are:

• solar panels - a 10kW system will generate a minimum of 15,000 kilowatt hours (kWh) of energy per annum. Collectively, ACT public schools will generate around 1.962 million kWh per annum. This will provide an ongoing income stream for schools totalling around $780,000 per annum ($15.6 million over 20 years) to be reinvested by schools to further reduce carbon emissions.

• lighting upgrades - this work is expected to achieve energy savings of around 30 per cent.

• insulation - this work is expected to reduce energy costs by a further 20 per cent.

• PC Power Management - this is expected to reduce personal computer energy costs by around 60 per cent.
